From Britain's textile mills and steam engines to Marx's call for revolution — how the Industrial Revolution transformed Europe's economy, created new social classes, and produced the ideologies, reforms, and conflicts that would define the modern world.
Six ways to master Unit 6 — pick whichever fits how you like to study.
Seven topics from the College Board CED, in order.
Unit 6 traces how Britain's early advantages in coal, iron, and textiles ignited the first Industrial Revolution, soon spreading to Belgium, France, and Germany as railroads, the factory system, and new energy sources reorganized production. A Second Industrial Revolution later added steel, chemicals, and electricity, deepening Europe's economic transformation. Classical liberals extended Adam Smith's laissez-faire ideas into the industrial age, defending free markets and minimal government intervention even as industrialization generated dramatic new inequalities.
Those inequalities provoked powerful responses: Karl Marx and Friedrich Engels' Communist Manifesto reframed industrial society as a class struggle between bourgeoisie and proletariat, inspiring socialism and trade unions, while utopian socialists imagined cooperative alternatives to capitalism. Meanwhile, rapid urbanization created overcrowded cities, public health crises, and a new industrial working class — including widespread child labor — that eventually provoked reform movements like Chartism and the passage of factory acts. At the same time, a rising middle class embraced new consumer goods and domestic gender roles, while thinkers proposed Social Darwinism to explain (and justify) the era's stark inequalities. This unit is roughly 8–12% of the AP European History exam.
The College Board ties Unit 6 to four of its course-wide themes:
